STONEBEAR
STONEBEAR
The depth is controlled by an articulating drawbar.
The Stone rake collects the stones to the drum.
The collecting drum of SB4000 has a rotor with 18 and SB5200 24 Kongskilde tines.
Separate hydraulic folding cylinders are alternative equipment.
Rake and Collect in one operation
Utilizing adjustable depth control wheels, the Stonebear rakes are designed to follow the contours of uneven fields. The rakes rotate in the opposite direction to forward travel. The heavy duty spikes, made of high tensile steel in a spi-ral arrangement, draw the stones to the center of the machine onto the sieve.
The depth of the sieve is controlled hydraulically through an articulating drawbar. The stones are sieved by tines in a rotor over the exchange-able sieve. The tines then throw the stones into the hopper. Extra soil and smaller stones go through the sieve and back onto the ground.
When the storage hopper is full. A unique hydraulic dumping system allows easy discharge directly into a dump trailer, truck or pile in the corner of the field.
Quality and Durability
The Kongskilde Stonebear is a solid structure of high quality material,designed for a long working life.
The power transmission consists of V-belts to protect against overload and absorb shock forces when the drum or rakes engage a large stone.
The heavy duty vibrant Kongskilde tines, engage the drum sieve and throw stones into the hopper. The unique Kongskilde tine is made from convex steel, with a specially developed shape for optimal strength. A helperspring supports the tine to assist movement of large stones from the collecting drum.

Removing stones the easy way
The Kongskilde Stonebear is specially designed for the re-moval and collection of stones from cultivated land in one operation. It can also be used in the con-struction industry to clean sites, golf courses, sport fields, turf sod operations etc.
The Stonebear is designed to collect stones from approx. 2,8 cm to 30 cm. A working width of 4m or 5.2m provides for a one-man operation, with greater capacity and efficiency.
The Stonebear is equipped with wide low-pressure tires, to reduce compaction and tracks in the field. This wide, low-pressure tire de-sign allows the Stonebear to be used effectively before drilling and planting operations.
The hopper has a tipping height of 2.3 metre.
Adjustable double wheels con-trol the depth of the SB 5200 stone rakes.
The rotor is powered by a reversing gearbox and a straight V-belt pulley.
A V-belt pulley powers the stone rakes.
Large Hopper The new hopper design on the Stonebear is 20% larger with a 1.8 cu. m capacity. The hopper has small holes in front to indicate the level and inform the operator for emptying. The inside rear section is covered with a heavy-duty replaceable mat for protection and sound reduction. The hopper pivots on replaceable bushings on a heavy shaft across the full width of the tank. Smooth, convenient tipping is achieved at a height of 2.3 m.
Versatile Machine
The Stonebear can be used for many applications. Most popular for agricultural use, to save labor, machine operations and protection against damage to harvesting machinery. The Stonebear is also popular in construction and recrea-tional applications for collection of stones, trash, small roots etc. It is often used for turf sod, golf course, sports arenas and road preparations.
Best results are achieved when the soil is dry and cultivated. The Kongskilde Stonebear as a one-man operation, pays its investment. Stones can also be sold for roadside protection and landscaping. A V-belt pulley powers the stone rakes.

Transport The stone-rakes on the Stonebear are raised either mechanically or hydraulically in one smooth opera-tion by single acting hydraulic cylinders. Upon completion to the folded position, with lock pins in place, a narrow transport width of 2.6m is achieved for convenient and safe road transportation. The Stonebear tows smoothly at rated tractor road speeds.
Tractor requirementsUnlike many conventional stone picking machines, the Stonebear operates with a low tractor power requirement; SB 4000: 55 KW (72 hp) and SB 5200: 60kW (80 hp). An operation speed of 350 rpm is recommended for proper field op-eration. Minimum hydraulic require-ments are two single acting outlets. Tractors equipped with two pairs of outlets provide for the convenience of dumping and folding rakes.
